Dysglycemia and a history of reproductive risk factors
1Department of Obstetrics and Gynecology, Division of Maternal-Fetal Medicine, McMaster University and Hamilton Health Sciences, Hamilton, Ontario, Canada mcdonals{at}mcmaster.ca ABSTRACT Objective: To identify reproductive risk factors associated with dysglycemia (diabetes, impaired glucose tolerance, and impaired fasting glucose) in a contemporary, multiethnic population. Research Design and Methods Study Design: We studied 14,661 women screened with an OGTT for the DREAM Trial. Reproductive risk factors were compared in normoglycemic and dysglycemic women. Results: Dysglycemia was significantly associated with the number of children born (OR 1.03 per child, 95% CI 1.01-1.05), age (OR 1.05 per year, 1.04-1.05), non-European ancestry (OR 1.09, 1.01-1.17), pre-eclampsia/eclampsia (OR 1.14, 1.02-1.27), irregular periods (OR 1.21, 1.07-1.36), and GDM (OR 1.53, 1.35-1.74). The relationship between GDM and dysglycemia did not differ across BMI tertiles (p=0.84), nor did the relationships of other risk factors. Conclusions: Reproductive factors, particularly GDM, are associated with dysglycemia in middle-aged women from many ethnicities. Reproductive factors can be used to counsel young women about their future risk of dysglycemia, while in middle age they may help screen for dysglycemia.
